Application filed September 18, 1889; Serial No. 324,334. (No model.)

To all whom it may concern:

Be it kn own that I, WATSON R. ROOT, a ci tizen of the United States, residing at Canton,

, in the county of Hartford and State of Conwork automatically, and consequently more necticut, have invented certain new and useful Improvements in Machines for Lining Rules, of which the following is a specification.

My invention relates to machines for making the longitudinal lines on rules or other articles; and the chief object of my invention is to provide a machine for doing this expeditiously and better than heretofore.

In the accompanying drawings, Figure 1 is a plan view of my machine. tical section thereof on line 00 m of Fig. 1. Fig. 3 is a rear elevation thereof. Fig. 4 is a vertical section on the line 22 of Fig. 2. Fig. 5 is a detached enlarged view of the markingpoints and their mountings. Fig. 6 is a plan View of the same, partly in horizontal section. Fig. 7 is a vertical section on line w w of Fig. 5, partly in elevation; and Fig. 8 is a rear View of the same with one of the rock-shafts in section.

A designates the frame, upon which are mounted two pairs of shafts a, bearing elastic feed-rollers 9 9, the same being preferably formed of soft rubber. One of these shafts is made longer than the others and provided with the driving-pulley B, Fig. l, and the respective shafts are provided with gears 11, which are connected by the intermediate gear 0, whereby both pairs of rollers revolve in unison in the same direction;

Extending through the machine from right to left at right angles to the axes of the rollers 9 9 there is an opening or passage-way 10, Figs. 1 and 2, one side wall of which may serve as a guide for the passage of the rules to the rollers. Between the pairs of rollers I arrange the marking points, preferably in four series, for lining or marking simultaneously the opposite sides of a folded rule. I arrange the upper and lower series in one block upon one side of the passage-way for marking one half of a folded rule, and in a companion block I place two like series upon the other side of the passage-way for mark- Fig. 2 is a vering the other half of said rule. 11 11 designate these blocks, which are secured to the frame of the machine in any proper manner in the position shown in Figs. 1 to 4, inclusive. These blocks are bored horizontally from front to rear and provided with a number of rock-shafts 12. In order to avoid crowd= ing, the smaller parts have their figures or letters of reference placed on them only in the-enlarged views, Figs. 5, 6, 7, and 8.

Each of the tool-bearing blocks is provided with a ledge or bracket 13 upon the inner face, which serves as the bed for one side of the rule as it passes along by the marking-points. The marking-points are set in the inner ends of the rock-shafts 12 with their sharpened ends projecting against the rule or into the path of the rule, the broken lines in Fig. 5 indicating a rule as being passed through between the points. Each rock-shaft is pro- -vided With an arm or eye 14 for the attachment of springs 15, the other ends of which springs are attached to some stationary pointas, for instance, the posts 16. These springs have a tendency to turn the rockshafts and swing the points of the markingtools in a direction to press them against the opposite sides of the rule. The points are set in the rock-shafts so as to bringthem'into different planes for marking different lines, and their number and-position may be varied according to the work desired. These rockshafts are to have a degree of rocking motion for swinging the points, and some means must be provided for confining them against longitudinal movement. As a convenient means of placing and securing these rock-shafts, in place, I notch them upon one side, as shown. at 17, and secure them by a plate 18, that is fastened to the outside of the blocks 11. These plates are each provided with a slot 19, the position of which is coincident with the respective rock-shafts, so that the plates may be slipped over the shafts with the metal at one side of the slot 19 in the notch 17 of each V shaft, as shown in Figs. 6, 7, and 8, whereby the rock-shafts areheld against alongitudinal movement and at the same time permitted to have a certain range of rocking movement. The blocks and tools upon both sides of the rec bed will be the same, with the exception that the blocks have their tools arranged to form right and left handed lines, respectively, so that when the blocks are placed face to face the marking-tools will all slant toward that side of the machine to which the feed-rollers will carry the rule. The blocks will also be set such distance apart that their con-fronting faces Will engage the opposite edges of the rule, or in lieu thereof other gages may be provided. An ordinary four-section rule or a two-section rule is folded on the joint that brings the-halves of the rule together gilh their edges abutting, but otherwise left a The operator passes a rule between the first pair of rollers, which grasp the-rule-and force it between the marking-points for marking. the: longitudinal lines thereon, and be-- fore-thdfirst pair of rollers release their hold uponthe-rule it iscaught by the second pair,
